Waterfalls near Nagarjuna Sagar...Well waterfalls are generally formed at the younger stage of river when it flows through canyons and on plateaus.....It is also a place for various species of animals like crocodiles, salmons, bears, and birds....the water after it falling from the top flows at very high speeds they can lead to whirlpools which is disastrous and a nightmare for a water sportsmen or fisherman..
